Incidentally, the Neckline from where BankNifty had an H&S breakdown, was also the Neckline of an Inverted H&S recently. However, in this case, it has failed to breakout. Upward Inclined Inverted H&S Necklines have this trait of failure. Third Black Day in succession (not the best formation of Three Black Crows), I'll be watching for supports below 30500 though nothing can be preempted at this moment.
